Immunity To Ostertagiasis In Calves, Leo F. Lejambre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parasites are responsible for heavy economic loss to the livestock industry. The losses in cattle due to parasitism can only be roughly estimated, since many cattle do not die or become visibly sick. However, there are more subtle losses such as reduced growth rate, and decreased meat and milk production (Levine, 1961). In 1954 the U. S. Department of Agriculture published an estimate of the losses in agriculture over the 10 year period, 1942-1951. At that time, the best judgement of specialists in the Department of Agriculture placed the annual loss to parasitism in cattle at $19,026,000 of which $8,989,000 …

Studies On Amino Acid Balance In Three Fish Meals, Krachang Wisutharom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

High levels of fish mean cannot be used in chick diets in the United States because of the relatively high cost as compared to soybean meal. In certain areas or countries where large amounts of fish meal are produced, it may be economically feasible to use fish meal as the major protein supplement in the poultry rations.

Feed consumed by poultry must provide most of the materials the birds need for growth or to produce eggs. Those who formulate feed must select ingredients and combine them in proportions which will allow the bird to grow or produce eggs at the …

Voluntary Intake Of Forage By Holstein Cows As Influenced By Lactation, Gestation, Body Weight, And Frequency Of Feeding, W. L. Johnston, G. W. Trimberger, M. J. Wright, L. Dale Van Vleck, C. R. Henderson

Department of Animal Science: Faculty Publications

Relationships involving forage appetite and frequency of feeding forage were studied with high-producing Holstein cows, including 60 complete cow lactations and 49 records of the dry period. Significant correlation (r= .59) was obtained between forage dry matter intake and 4% FCM yield in the lactation period. Patterns of forage DM intake were affected strongly by different stages of the lactation and dry periods. Infrequent periods of hot summer weather decreased intake and milk yield by about 10%. Individual cow differences, however, were the most important source of variation in forage DM intake. Age, body weight changes, body condition, and stage …

Good Management For The Springers Pays Dividends, J Y. Langdon

Journal of the Department of Agriculture, Western Australia, Series 4

This article gives a striking example of the advantages of calving cows in good and rising condition—and explains why condition around calving time is so important.

ALTHOUGH most farmers know that cows calving in good and improving condition will give higher yields than those calving in poor condition, few use this knowledge to improve the production from their cows.

Stocking Rates On Cyprus Barrel Medic In The Northern Wheatbelt, R J. Parkin

Journal of the Department of Agriculture, Western Australia, Series 4

IN May 1963, some three weeks after germination, a 4th year stand of Cyprus barrel medic was stocked with Merino wethers.

These same sheep are still grazing the area after three years.

Twinning Increases Production, K P. Croker

Journal of the Department of Agriculture, Western Australia, Series 4

Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.

But recent experiments have proved otherwise and agricultural scientists now agree that . . .

TWINNING INCREASES PRODUCTION

THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.

Certainly, lambing percentages are low when compared with those of most British breeds of sheep.

Meadow Hay For The Dairy Herd, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

CONSERVATION is the basis of progress in dairy farming and the major form is meadow hay, but unfortunately relatively few dairy farmers give enough attention to the quality and quantity of this important feed.

The First Year Of A Cattle Stocking Rate Trial At Pardelup, R Sprivulis

Journal of the Department of Agriculture, Western Australia, Series 4

AS a first step towards the study of pasture utilisation by cattle, a simple trial was commenced at the Pardelup Prison Farm in 1964.

The trial is carried out with Poll Hereford cross steers set stocked on Mt. Barker subterranean-clover and Wimmera ryegrass pasture.

It will be repeated for several seasons.

Reproductive Wastage And The Sheep Shortage In Western Australia, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

WESTERN AUSTRALIA has an acute shortage of sheep.

It is estimated that about seven million extra sheep are needed to stock existing pastures fully; meanwhile the carrying capacity of the State's pastures is increasing at the rate of three million sheep a year.

Continuous Grazing On Rose Clover At Northampton, R J. Parkin

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of its upright growth habit, it is often thought that rose clover may require some form of specialised grazing management.

It has also been said that the sheep find the plant and in particular the seed head, undesirable in the dry stages.

However, more recent observations refute this (Bailey 1966). The present commonly-grown strains of rose clover are later flowering generally than the medics or Geraldton subterranean clover and stay green later in the season.

Heavy Rate Set Stocking : Esperance Downs Research Station, R J. Doyle

Journal of the Department of Agriculture, Western Australia, Series 4

THIS article describes a stocking rate demonstration in one paddock at Esperance Downs Research Station, using Merino wethers.

Since December 1961, the area has supported 530 to 540 Merino wethers under continuous grazing.

Egg Shell Quality, R J. Bishop

Journal of the Department of Agriculture, Western Australia, Series 4

Recent overseas work and local industry developments indicate that the calcium content of feed for laying hens in Western Australia should be increased to achieve satisfactory egg shell strength.

Age, temperature and breeding are other important influences on egg shell quality.

More Sheep Per Acre, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

In the late 1950's agricultural scientists in Western Australia became convinced that much of the improved pasture in the agricultural areas of the State was going to waste.

The results of the early trials resulted in many farm demonstrations of higher carrying capacities on improved pastures in southern agricultural areas.

Stocking Rates On Light Land : Wongan Hills Research Station, R J. Lightfoot, W. L. Mcgarry

Journal of the Department of Agriculture, Western Australia, Series 4

THE two most important things that determine the rate of return on invested capital in Merino sheep breeding and grazing are the stocking rate and lambing percentage.

Rate Of Stocking, Rate Of Fertiliser In The Chapman Valley, R J. Parkin

Journal of the Department of Agriculture, Western Australia, Series 4

THE Chapman Valley embraces a relatively small area of country, following generally the course of the Chapman River.

The Chapman Valley proper extends from just north-east of Geraldton to Nanson, Nabawa and Naraling and includes on its fringes, areas of Narra Tarra, Moonyoonooka and areas west of Nabawa towards Northampton.

The Avondale Stocking Rate Experiment, L D. White, R. J. Lightfoot, R. N. Glencross

Journal of the Department of Agriculture, Western Australia, Series 4

THERE is now ample evidence that stocking rates well above the usual district levels can be carried in the Avon Valley.

However, many aspects of increasing stocking rates still require investigation, particularly with lambing ewes and young sheep.

Stocking Rate And Rate Of Superphosphate In A Higher Rainfall Area, P P. Mann, B. J. Gorddard, R. N. Glencross, E. N. Fitzpatrick

Journal of the Department of Agriculture, Western Australia, Series 4

In its virgin state the area carried a forest association of red-gum and jarrah, and the soils are typical of large areas in the south-west of Western Australia.

These gravelly soils have a high requirement for phosphate during their first years under pasture, and this trial was designed to investigate the relationship between rate of phosphate, stocking rate and pasture production over a number of seasons.

Values Of Commonly-Used Protein Supplements In Broiler Rations, D F. Hessels

Journal of the Department of Agriculture, Western Australia, Series 4

THE performances of broiler flocks in the latter part of 1964 were below standard. Low body weights and a high incidence of gizzard erosion were common on farms.

It was therefore decided to test the biological valuss of the commonly-used protein supplements and also to try to find a correlation between gizzard erosion and any of the protein supplements.

Animal Husbandry Research At Bramley, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

A progress report of animal husbandry investigations at the Bramley Animal Husbandry Research Station, Margaret River.

BRAMLEY RESEARCH STATION is four miles north of Margaret River.

The average annual rainfall of 45 inches falls mainly in the winter, providing a seven-month growing season which starts in March or April.

The June-July period is excessively wet, causing extensive waterlogging of the soils.

1966 Beef Cattle Progress Report Of Research Activities, E. F. Frolik, H. H. Kramer

Nebraska Beef Cattle Reports

Many beef cattle breeders in the United States and other countries are following the progress of the selection experiment at the Fort Robinson Beef Cattle Research Station, Crawford, Nebraska. Three lines of Hereford cattle from the same genetic foundation are under selection. Line 21 is selected for 200-day weight. Line 22 is selected for yearling weight. Line 23 is selected for an index combining yearling weight and a score for muscling and fat thickness.

Each line is operated as a closed herd so it will be possible to determine how much improvement in economic traits can be made by selecting …

Comparisons Of Broiler Rations, D F. Hessels

Journal of the Department of Agriculture, Western Australia, Series 4

PELLETS are the most profitable feed for broiler chickens—but when they contain about two-thirds cereal, does it pay a country grower to pay freight on pellets when cereals are plentiful in his district?

Relationships Among Some Physical And Chemical Parameters Of Full- Versus Limited-Fed Yorkshire Pigs Slaughtered At Different Live Weights, G. M. Babatunde, W. G. Pond, L. Dale Van Vleck, G. H. Kroening, J. T. Reid, J. R. Stouffer, G. H. Wellington

Department of Animal Science: Faculty Publications

An experiment was designed using 30 Yorkshire pigs to study the influence of slaughter weight and feed restriction on carcass cut-out data and to relate these physical measurements to the chemically-determined proximate components. As slaughter weight increased from 79 to 102 kg., the percent of all lean cuts decreased significantly, while that of fat cuts and back-fat thickness increased significantly. Absolute amounts of both fat and lean cuts increased with slaughter weight. Feed restriction significantly increased most of the lean parameters studied and reduced the fat measurements. It increased percent of head and reduced the percent of offal (gastrointestinal tract …

The Effect Of Methods Of Storage On The Gross Energy, Chemical Composition And Feeding Value Of Alfalfa, Guru Prasad Mohanty

Electronic Theses and Dissertations

Production of good quality hay or silage and its proper storage without loss of the nutritive value is an important problem for dairy farmers. They are particularly interested in meeting the energy needs in feeding their herds for milk production. During the past decade there has been a substantial increase in the volume and intensity of research towards the nutritional and calorimetric aspects of cattle feeds. A number of unavoidable problems come in the way of their application causing financial disaster in today’s competitive economy of dairy farming. To increase milk production or to maintain a high level of production, …

Stocking Rates With Growing Cattle At Wokalup Research Station, Maurice C. Cullity

Journal of the Department of Agriculture, Western Australia, Series 4

CONSIDERABLE attention has been given in Australia and in overseas countries to methods of grazing control, and to the effects of varying stocking concentrations.

There is evidence that the highest yields per animal—of milk or butterfat per cow, or of weight increase per growing or fattening beast—are not necessarily a true reflection of the greatest output from the farm, as indicated by the measure of yield per acre.

A Sick Ewe Why? [Pregnancy Toxaemia], F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

THIS dazed-looking ewe was seen wandering aimlessly around with an unsteady gait.

Three other ewes had died after a similar sickness lasting about four days.

Two more sheep in the flock of 350 ewes were also sick. One of them was down with its head on one side.

Skim Milk : Is A Valuable Pig Feed, But It Should Be Balanced By Other Foods, P Mcnamara, R. Sprivulis

Journal of the Department of Agriculture, Western Australia, Series 4

SKIM milk is a source of high quality protein, and as such is a valuable feed for young pigs.

Pigs will live and grow on skim milk alone, but it is not a balanced food. You will not get the best out of the milk or the pigs if the diet is not balanced by other foods.

List Of Registered Stock Foods And Stock Licks, 1965-66, H G. Cariss

Journal of the Department of Agriculture, Western Australia, Series 4

A l l foods for stock sold in Western Australia are required by the Feeding Stuffs Act, 1928-1955, to be registered annually with the Department of Agriculture.

For the purposes of the Act, "Food for Stock" includes stock licks, which in turn embrace all preparations claimed to supply or primarily intended to supply mineral matter to stock.
